PURPOSE Recent studies have shown that mesenchymal stem cells (MSCs) obtained from bone marrow transplantation patients originate from the host. This clinical observation suggests that MSCs in their niches could be resistant to irradiation. However, the biologic responses of bone marrow MSCs to irradiation have rarely been described in the literature. (More)
INTRODUCTION Diffuse alveolar damage (DAD) is the pathological hallmark of acute respiratory distress syndrome (ARDS), however, the presence of DAD in the clinical criteria of ARDS patients by Berlin definition is little known. This study is designed to investigate the role of DAD in ARDS patients who underwent open lung biopsy. METHODS We retrospectively(More)
Silencing of Wnt antagonists with aberrant activation of Wnt signaling is a common phenomenon in various human cancers. Wnt inhibitory factor-1 (WIF-1) is a secreted antagonist of Wnt signaling and acts through direct binding to Wnt in the extracellular space. In this study, we tried to illuminate the impact of WIF-1 gene expression in melanoma with WIF-1(More)
BACKGROUND Previous studies have found an association between obstructive sleep apnea (OSA) and chronic kidney disease (CKD). However, subjects with confounding factors such as diabetes and hypertension were not excluded. The purpose of the present study was to determine whether patients with OSA without meeting criteria for diabetes or hypertension would(More)
In typical RSA, it is impossible to create a key pair (e, d) such that both are simultaneously much shorter than φ(N). This is because if d is selected first, then e will be of the same order of magnitude as φ(N), and vice versa. At Asiacrypt’99, Sun et al. designed three variants of RSA using prime factors p and q of unbalanced size. The first RSA variant(More)
Second primary cancer is prevalent in patients with head and neck cancer (HNC), for which esophagus and lung are the most usual sites, associated with an extremely poor prognosis. However, information regarding the actual risk of second primary esophageal or lung cancer in South-east Asia, the betel-quid chewing area, has been restricted to data from(More)
BACKGROUND Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is the standard therapy for advanced lung adenocarcinomas with common EGFR mutations. Preclinical studies have suggested that uncommon G719X, L861Q, and S768I mutations are also sensitive to EGFR-TKIs. However, the efficacy of EGFR-TKIs in patients with these uncommon mutations(More)
Mechanical ventilation in patients may increase the risk of an acute lung injury (ALI), termed ventilator-induced lung injury (VILI). Induced pluripotent stem cells (iPSCs) have previously been shown to improve tissue repair in different disease models, including ALI. However, the therapeutic efficacy of iPSCs-derived conditioned medium (iPSC-CM) on ALI or(More)
The use of Synthetic Amphiphile INTeraction-18 (SAINT-18) carrying plasmid pigment epithelium-derived factor (p-PEDF) as an anti-angiogenesis strategy to treat corneal neovascularization in a rat model was evaluated. Four partially dried forms (Group A: 0 microg, B: 0.1 microg, C: 1 microg, D: 10 microg) of a p-PEDF-SAINT-18 were prepared and implanted into(More)
Expression of survivin has been reported to be correlated with shorter survival in patients with non-small cell lung cancer (NSCLC), and overexpression of survivin may lead to radioresistance in various human cancers. In this study, we inhibited survivin expression by using an adenoviral vector (AdsiSurvivin)-mediated RNA interference to elucidate the(More)
